使用相同的 url 但每次都传递不同的 ID 来发出 800 多个 get 请求的最快方法

Question

从包含 800 多个设备 ID 的 excel sheet 加载设备 ID 并在 http get 请求中传递这些设备 ID 的最快方法是什么。

我正在从 excel sheet 获取设备 ID，发出 http get 请求以获取相关数据并将其转储到列表中，然后将其保存在 excel文件使用：-

if __name__ == '__main__':
    excel_file = openpyxl.load_workbook("D:\mypath\Book1.xlsx")
    active_sheet = excel_file.get_sheet_by_name("Sheet4")

    def iter_rows(active_sheet):
        for row in active_sheet.iter_rows(): 
            yield [cell.value for cell in row]

    res = iter_rows(active_sheet)
    keys = next(res)

    final_data_to_dump = []
    failed_data_dump = []

    for new in res:
        
        inventory_data = dict(zip(keys, new))
        if None in inventory_data.values():
            pass
        else:
            
            url_get_event = 'https://some_url&source={}'.format(inventory_data['DeviceID'])

            header_events = {
            'Authorization': 'Basic authkey_here'}

            print(inventory_data['DeviceID'])
            try:
                r3 = requests.get(url_get_event, headers=header_events)
                r3_json = json.loads(r3.content)
                if r3_json['events']:
                    for object in r3_json['events']:

                        dict_excel_data = {

                            "DeviceID":object['source']['id'],
                            "Device Name":object['source']['name'],
                            "Start 1":object['Start1'],
                            "Start 2":object['Start2'],
                            "Watering Mode":object['WateringMode'],
                            "Duration":object['ActuationDetails']['Duration'],
                            "Type":object['type'],
                            "Creation Time":object['creationTime']
                        }

                        final_data_to_dump.append(dict_excel_data)
                else:
                    no_dict_excel_data = {

                            "DeviceID":inventory_data["DeviceID"],
                            "Device Name":inventory_data["DeviceName"],
                            "Start 1":"",
                            "Start 2":"",
                            "Watering Mode":"",
                            "Duration":"",
                            "Type":"",
                            "Creation Time":""
                        }

                    final_data_to_dump.append(no_dict_excel_data)

            except requests.ConnectionError:
                failed_dict_excel_data = {

                        "DeviceID":inventory_data['DeviceID'],
                        "Device Name":inventory_data["DeviceName"],
                        "Status":"Connection Error"
                    }

                failed_data_dump.append(failed_dict_excel_data)
    df = pd.DataFrame.from_dict(final_data_to_dump)
    df2 = pd.DataFrame.from_dict(failed_data_dump)
    df.to_excel('D:\mypath\ReportReceived_10Apr.xlsx',sheet_name='Sheet1',index=False)     
    df2.to_excel('D:\mypath\Failed_ReportReceived_10Apr.xlsx',sheet_name='Sheet1',index=False)

但这可能需要 10-15 分钟以上的时间，因为 Book1 sheet 中有 800 多台设备，而且可能还会增加。我怎样才能使这个过程更快？

Answer 1

您可以使用异步库，但最简单的解决方案是执行类似

的操作

from concurrent.futures import ThreadPoolExecutor

with ThreadPoolExecutor() as exc:
    responses = exc.map(get, device_ids)

def get(device_id):
    url_get_event = 'https://some_url&source={}'.format(device_id)
    return requests.get(url_get_event)

如果代码的其他部分很小，您可能希望将函数提交给执行程序并使用 as_completed 在主线程中处理它们，同时等待对运行的其他请求.
